Re-emerging as a high-potential arena for both hydrocarbon and minerals exploration, the Neuquén Basin has been estimated to contain more than 250 trillion cubic feet (40 billion barrels of oil equivalent) of unconventional natural gas in both tight sands and shales. Analysts now believe the basin could produce several billion barrels of oil equivalent in the decades ahead.
Although several seismic and non-seismic datasets have been acquired in the area, the coverage is not uniform and no entity has yet integrated all of the available data into a single, cohesive interpretation. As a result, operating companies have turned to NEOS GeoSolutions – a Houston-based provider of surface and subsurface imaging solutions – to recommend an alternate approach…

NEOS presented at the Geophysical Society of Pittsburgh (GSP), a nonprofit organization dedicated to promoting the science of geophysics in the Appalachian Basin. NEOS’s Dr. Craig Beasley, Vice President of Exploration, presented “Unlocking the Potential of Appalachia,” a talk in which Dr. Beasley shared highlights from several recent multi-measurement interpretation (MMI) projects in the region.
Over the last year, NEOS has undertaken MMI studies to image the surface and subsurface in key exploration and development areas within the Appalachian Basin. NEOS’s multi-measurement methodology involves: 1) acquiring a series of airborne, non-seismic datasets (gravity, magnetic, radiometric, electromagnetic, and hyperspectral); 2) integrating these newly acquired datasets with existing seismic, well log, and production information; and 3) simultaneously interpreting the results.
Although deliverables vary based on the unique objectives of a project, interpretation results focused on:
Detecting orphaned wellbores;
Mapping faults throughout the geologic column;
Identifying oil seeps and gas plumes on the surface, and tracing their likely migration pathways (including via wellbores and faults);
Mapping lateral and vertical variations in the region’s aquifers;
Highlighting zones of increased gas concentration, both trapped in the near-surface and surrounding the Marcellus Shale interval;
Integrating seismic, non-seismic, and well log data to create county-scale, 2-D and 3-D structural and stratigraphic models;
Mapping reservoir sweet spots using multivariate, geo-statistical ‘predictive analytics’ models.
